EXPLOSIVE TOY.

Specification of Letters Patent.

Patented July 17, 1906.

T0 alt whom it may concern:

Be it known that I, GUSTAF A. OBERG, a citizen of the United States, residing at Albuquerque, in the county of Bernadillo and Territory of New Mexico, have invented certain new and useful Improvements in Explosive Toys, of which the following is a specification.

My invention relates to improvements in explosive toys, and has reference to a means for the explosion of small fulminating caps or parcels of explosive material as an amusement.

The object of the invention is to provide a hollow cane and mount mechanism suitably within its handle and stem in a manner so that when the end of the cane is struck upon the ground or pavement one of the caps or parcels will be exploded at or near the ground.

The use of my invention affords an interesting and harmless amusement. The devices employed are of few parts, and the toy is not expensive in construction, comparatively speaking. The novel means employed are fully described herein and illustrated by the drawings, wherein Figure -1 represents a vertical elevation of the invention, showing the handle and cylindrical stem, the latter being broken away, so that the devices at the lower part of the stem may be shown in the same figure, and showing an end view of pinion 6, the view be ing mostly in section. Fig. 2 represents a top view of the handle. Fig. 3 represents a side view of pinion 6 and band 10, mounted thereon. Fig. 4 represents a perspective view of the rack-bar. Fig. 5 represents a vertical front view of the plunger. Fig. 6 represents a top view of the plunger, and Fig. 7 represents a portion of the stem of the cane.

The devices which I now explain are for the purpose of conveying the parcels of explosive material so that each parcel will become seated upon the lower surface of pinion 6, at which point it is exploded by the movable block 15, the conveying movement being effected by the band 10, actuated by the rack-bar 21 upon wheels 23 and 24.

I construct a suitable cane handle 1, mounted upon a cylindrical stem, the latter having a length similar to ordinary canes. The stemhas a shell-like body, the wall thereof being represented by the numerals 2 and 3, extending continuously from the handle 1 to the lower end of the cane at 4. Suitably journaled in the wall of the cane, asat 5, I

mount the pinion 6 upon its removable pivot 7, and upon the cane-head above the hollow part of the stem I pivotally mount the pinion 8 upon its pivot 9 within the opening 28. Upon the pinions 6 and 8 I mount the band 10, upon which are adhesively placed the explosive caps 11, equally spaced apart. As thus described, these pinions are free to rotate, and the endless band 10 is adapted to have frictional contact thereon and a movement from one pinion to the other, carrying upon its surface the series of explosive caps 11, the power for such movement being hereinafter described. The lower end of the stem is provided upon its inner wall with stationary lugs 12 and 12, and the open lower end of the stem is provided with an annular rim or ring 4, screwed upon the bottom, which also performs the function of a stop-lug.

I construct the plunger 13, having a heavy metal base 14, and upon the latter is formed the exploding-block 15. The plunger is pro vided with an enlarged rim 16 at its upper circular edge and a raised rim 17 upon its body, which perform the function of stoplugs, and the plunger is adapted to slide freely upward and downward, the upper portion of its wall being always within the stem of the cane, such movement being lengthwise and between lug 12 and rim 4.

A suitable opening 18 is provided in the base 14, Fig. 6, and pivotally mounted therein at 19 is the rack-bar head 20, the rack-bar 21 being integral therewith and adapted to extend lengthwise within the body of plunger 13. The rack-bar head 20 is formed with an inclined outer wall, and the rack-bar is provided with transversely-formed teeth 22.

The pinion 6 is provided with toothed wheels 9 23 and 24, adapted to form a gear with rackbar 21.

From the description it will be understood that when the cane is struck upon a solid substance, as upon a pavement, the rack-bar 21 will be thrown sidewise or forwardly in a direction toward pinion 6, resulting in a gear contact thereof with the teeth of wheels 23 and 24, this contact being dueto the fact that the head 20 is formed with an inclined. outer wall, the pivot 19 being eccentrically placed. The force of the downward blow causes the rack-bar while moving forward and upward to actuate pinion 6 and rotate it in a direction to cause band 10 to advance and pass over pinion 6. The caps 11 are s aced apart at suitable intervals, so that the istance traversed by the rack-bar while in gear, each stroke, will equal the distance apart of the explosive caps, and the band is adjusted so that one of the caps 11 will be seated upon the lower surface of pinion 6 at the moment block 15 in its upward course strikes upon the cap on pinion 6.

A flexible non-combustible substance is used in the construction of band 10, and in operation the upward movement of rack-bar 21 and its gear-contact with wheels of pinion 6 are certain, the result of the movement being that a cap is exploded whenever the end of the cane is struck upon the ground. After the cap has been exploded rack-bar 21 by its own weight falls downward into operative position, since I provide the opening 25, which is greater than the width of rack-bar 21, and during the falling movement of the rack-bar pinion 6 remains at rest.

The pinion 8 is removable, and in assembling the parts the band 10, containing the adhesive caps', may be placed in position by passing it through the opening 28 in the canehead and placing it over pinion 6, the body of the cane being provided with an opening 30 for that purpose, as shown by Fig. 7. The end 4 is screwed on the stem after the plunger is placed in position.

When it is desired to use the toy as a cane without the explosive feature, the plunger is drawn upward within the stem, so that the head 20 may not have any contact, this being accomplished by means of a rod suitably placed and attached to the plunger, as the rod 26. The handle 27 of the rod is adapted to have a sidewise movement by means of the joint 28 and may be confined by the pivotally-mounted clip 29, and this affords a variety of uses for the cane.

In the construction a steel band may be used to good advantage provided with small pockets or indentations of-a size to accommodate the reception therein of the explosive cap, and the band may be readily removed from the cane, loaded, and replaced, since the pivots of pinions 6 and 8 are removable.

A light and cheap construction may be employed for the lighter variety of explosive caps, and for heavy detonating caps the parts may be constructed more substantial.

Various minor changes may be made in methods of construction without departing from the scope of the invention, as is obvious, the latter being determined by the claim.

That I claim as my invention is A new article of manufacture, consisting of an explosive toy, in combination, comprising a cylindrical member having an opening extending lengthwise of its body; explosive parcels; a pinion mounted upon said cylindrical member; an endless band revolubly mounted within said cylindrical member and adapted to convey said explosive parcels upon its surface; a plunger slidably mounted within said cylindrical member, said plunger being provided with the wall 13 the plungerhead 14 and the inwardly-projecting exploding-block 15; a rack-bar pivotally mounted within said plunger; said rack-bar being adapted to form an intermittent gear-contact with said pinion.

In testimony whereof I have aflixed my signature in presence of two witnesses.
